At Sinai God reminded Israel that he had carried them out of Egypt as on eagles' wings, and invited them to be his treasured possession, a kingdom of priests and a holy nation, if they kept his covenant (Exodus 19:4). The mountain was wrapped in smoke and fire, it shook, and the trumpet blast grew louder until the people trembled. Then God spoke the Ten Commandments.
“And God spoke all these words:”
The covenant was sealed with sacrifice and blood, and Moses, Aaron and the elders saw the God of Israel and ate and drank in his presence (Exodus 24:9). Moses then spent forty days on the mountain receiving the instructions for the tabernacle, where God would dwell among his people. Meanwhile, below, the people persuaded Aaron to make a golden calf (Exodus 32:1). Moses broke the tablets, interceded for the people, and God renewed the covenant, revealing himself as compassionate, gracious, slow to anger and rich in steadfast love (Exodus 34:6). Moses came down with his face shining (Exodus 34:29).
Centuries later Elijah, worn out and running for his life from Jezebel, walked forty days to Horeb. There God was not in the wind, the earthquake or the fire, but in a low, gentle whisper, and he sent his discouraged prophet back to work (1 Kings 19:8).
The New Testament looks back on Sinai. Stephen recalls the angel in the bush and the living words Moses received there (Acts 7:30). Paul uses Sinai as a picture of the old covenant (Galatians 4:24), and Hebrews contrasts the terrifying mountain with the joyful gathering at Mount Zion through Jesus (Hebrews 12:18).
